Snape in Snakes Clothing

A slight redesign of snape - this was originally going to be him as an adult, but instead i now imagine it as Severus in year 5/6 - maybe sometime after the tree incident - I imagine he must cut his hair sometimes.
I think his top-half's really good, but the lower section of the coat (which is supposed to have a kind of faux-leather/faux-snake-skin look to it) looks a little dodgy to me...hmmm...
In the words of the onnly true Snape, Rickman himself - "I'll get you lousy coat-end!"
